Spectroscopic and biochemical characterization of metallo-ß-lactamase IMP-1 with dicarboxylic, sulfonyl, and thiol inhibitors.

In an effort to probe the biophysical mechanisms of inhibition for ten previously-reported inhibitors of metallo-ß-lactamases (MBL) with MBL IMP-1, equilibrium dialysis, metal analyses coupled with atomic absorption spectroscopy (AAS), native state mass spectrometry (native MS), and ultraviolet-visible spectrophotometry (UV-VIS) were used. 6-(1H-tetrazol-5-yl) picolinic acid (1T5PA), ANT431, D/l-captopril, thiorphan, and tiopronin were shown to form IMP-1/Zn(II)/inhibitor ternary complexes, while dipicolinic acid (DPA) and 4-(3-aminophenyl)pyridine-2,6-dicarboxylic acid (3AP-DPA) stripped some metal from the active site of IMP but also formed ternary complexes. DPA and 3AP-DPA stripped less metal from IMP-1 than from VIM-2 but stripped more metal from IMP-1 than from NDM-1. In contrast to a previous report, pterostilbene does not appear to bind to IMP-1 under our conditions. These results, along with previous studies, demonstrate similar mechanisms of inhibition toward different MBLs for different MBL inhibitors.

Dance Movement Therapy with Children: Practical Aspects of Remote Group Work.

The global COVID-19 outbreak has forced psychotherapists to find creative ways to continue treating their clients from afar. Dance movement therapy emphasizes the body-mind connection and offers a unique mode of emotional intervention for supporting mental processes. The present study is the first to examine the distinctive qualities of group dance movement therapy in the context of remote emotional intervention with young children. Fourteen preschool children participated in six DMT meetings. The data generated three themes: 1. play as a platform for transforming technical complexity into an expression of the inner world; 2. accessories and props as means of motivation for movement and imaginative play; 3. playfulness-inhibiting conditions in settings of remote therapy. The discussion examines the significance of bodily expressions in remote therapy for understanding the needs of children in times of crisis and for getting acquainted with feelings and sensations which do not lend themselves easily to verbal expression.

The Potential Benefits of Dance Movement Therapy in Improving Couple Relations of Individuals Diagnosed With Autism Spectrum Disorder-A Review.

A review of current literature indicates that adults diagnosed with autism spectrum disorder (ASD) feel the need for intimate and sexual relationships and maintain such relationships despite and alongside their difficulties in emotional communication, social interactions, reciprocity, and verbal and non-verbal expression. This understanding calls for the development of intervention programs designed to support the specific needs and address the problems of couples where one partner is diagnosed with ASD. In view of the relevance and significant part played by body and movement in emotional development and psychotherapy, the present article offers a review of studies examining the contribution of dance movement therapy to both the quality of life and functioning of adults with ASD and therapeutic processes in couple therapy. This review aims to establish an infrastructure for the construction of intervention programs and for future studies designed to enhance the quality of life and independence of adults with ASD.

The "Muscles of the Psyche": From Body Literacy to Emotional Literacy.

Autism spectrum disorder (ASD) is a neuro-developmental condition, which requires a multi-disciplinary matrix of treatments, including functional, educational, and emotional interventions. The latter mode of treatment entails particular difficulties, inasmuch as the core deficits of this condition seem to challenge the very premises of traditional psychotherapy. Reciprocity, verbal, and symbolic expression and inter-subjective dynamics are often difficult to attain with clients diagnosed with ASD, and emotional treatment thus often turns out to be a frustrating process, which may well elicit questions as to the efficacy of psychotherapeutic emotional interventions. These core challenges, described in the literature, become particularly acute in view of the increasing number of clients diagnosed on the autistic spectrum in recent years, and the growing need for qualified therapists who have trained for working specifically with this condition. It seems, therefore, that it is high time for systematic research into the lived experience of therapists working with these clients in order to attain a better clinical and theoretical understanding of the condition itself and broaden the range of effective interventions. This study, informed by a phenomenological-hermeneutic approach which guided both the collection of data and its subsequent analysis, aims to address these issues by exploring the particular challenges faced by therapists in this field, the questions that come up in the process, modes of personal and professional coping, and the insights elicited by the therapeutic encounter. The research consisted of in-depth interviews with 28 practicing therapists from a broad range of clinical orientations, including dance/movement, arts, music, and drama therapists, clinical psychologists, and clinical social workers. The essential themes that emerged from the participants' responses and the analysis of the findings lend support to theoretical and developmental approaches, which focus on the primacy and the foundational role of the concrete body in inter-subjective relationships and in the therapeutic process, and indicate the potential efficacy of somatic and kinetic interventions. The clinical implications of this study are thus highly relevant to the training and support of therapists working with ASD, who should be encouraged to develop greater receptivity to non-verbal modes of interaction in the therapeutic process.

MBLinhibitors.com, a Website Resource Offering Information and Expertise for the Continued Development of Metallo--Lactamase Inhibitors.

In an effort to facilitate the discovery of new, improved inhibitors of the metallo--lactamases (MBLs), a new, interactive website called MBLinhibitors.com was developed. Despite considerable efforts from the science community, there are no clinical inhibitors of the MBLs, which are now produced by human pathogens. The website, MBLinhibitors.com, contains a searchable database of known MBL inhibitors, and inhibitors can be searched by chemical name, chemical formula, chemical structure, Simplified Molecular-Input Line-Entry System (SMILES) format, and by the MBL on which studies were conducted. The site will also highlight a "MBL Inhibitor of the Month", and researchers are invited to submit compounds for this feature. Importantly, MBLinhibitors.com was designed to encourage collaboration, and researchers are invited to submit their new compounds, using the "Submit" function on the site, as well as their expertise using the "Collaboration" function. The intention is for this site to be interactive, and the site will be improved in the future as researchers use the site and suggest improvements. It is hoped that MBLinhibitors.com will serve as the one-stop site for any important information on MBL inhibitors and will aid in the discovery of a clinically useful MBL inhibitor.
